- This work reports the modelling of the kinetics of supercritical extraction of oils from grape seed samples (obtained from a Portuguese industry), and from two sets of chia seeds - high oil content seeds (HOCS), and underutilized low oil content seeds (LOCS). A rigorous thermodynamic framework was applied to calculate the solubility in the supercritical solvent of the grape and chia seeds oils. The oils, for the purposes of modeling, were represented by triolein. Second order polynomial functions are then fitted to the solubility data and used in the kinetics model of Sovová and Stateva [1] to simulate the extraction curves in gPROMS ModelBuilder [2]. The qualitative and quantitative agreement between the experimental and simulated extraction curves in terms of yields was good (2% <AARD < 9%) taking into consideration the very complex nature of the systems examined.eng
